Variable Area Flow Meters
FGM1190 McMenon Glass Variable Area Flowmeter
Measurement made easy — robust and reliable glass tube flowmeter
Product overview
Glass Tube — FGM1190
The VA Master FGM1190 is a glass tube variable area flowmeter for the measurement of clear liquids and gases. The position of the float in the conical glass meter tube is proportional to the flow and is read directly on the scale fitted to the meter tube.
It is suited for flow measurements in many industrial sectors such as apparatus engineering, the food and beverage industry, water treatment systems and the chemicals sector.
Highlights
Key features and options.
- Precision tubes with guide surfaces, guide ribs or guide rod
- Standard stainless steel housing
- Easy disassembly of the meter tube due to the O-ring seal
- Meter tube and float can be replaced independently of each other
- Magnetically actuated alarm signalling unit available from size ½ in and up
- Four scale types: direct reading in flow units, percentage, DK/DS and millimetre
